I think there are many pieces of that puzzle floating around. Fastest replacement might be if someone can make an app to encrypt on device replies via email. but that's not all.. if a pw protected chunk was sent back to a buddypress activity or message reply and could be decoded there... then people could setup a wordpress/buddypress for family and a separate install for friends.. Options to get rss read of activity, or get emailed activity and replies. Could just email a reply back with a plugin, but that's currently in the clear. It could just be a notice that ScreenName X posted a reply on the Activity Group Y.. click to read.. and it's trivial to make those things private / login needed kind of privacy at that point. So solve email encrypt on device, send to server which I think can hold data encrypted with php 7, and it would need to be decrypted within wordpress/buddypress for friends / family there when they logged in .. then there are most of the other pieces for mutliple messaging different contacts and groups.. it's all there. I am sure there are other similar projects with similar hooks where a similar thing could be streamlined / integrated with just on device email, with options to beef up the privacy to make it better. Would be nice to addin sms texting to the mix for notifications and replies somehow. most people know using email, and buddypress can be very similar to fbook for layout, so familiar to most I think. It's all close.
